It is scientifically a different mineral than Diamond, and believed to have formed when meteoric Graphite fell to earth. When this happened, great heat and stress transformed the Graphite into Diamond, but it retained Graphite's hexagonal crystal lattice.ISTINGUISHING SIMILAR MINERALS. The only mineral that can possibly be be confused with Diamond is waterworn Quartz pebbles which may resemble waterworn Diamonds, but the hardness and luster of Diamond will easily differentiate the two.
